Barclay

Reginald Endicott Barclay III is a highly talented, but introverted systems diagnostic engineer. He served aboard the USS Enterprise-D, Jupiter Station, USS Enterprise-E. Later he was transferred to the Pathfinder Project endeavoring to return the USS Voyager to the Alpha Quadrant.

As part of his work on the Pathfinder Project, he created a holographic version of himself to send to Voyager. However, its transmission was intercepted by the Ferengi, and the hologram was modified to serve their nefarious purposes.
